During further checking consistency between left and bigbite scalars, 
new issues are found: LHRS ungated scalar counts ~1% more T1 than the 
one on bigbite:

When there is an observable inconsistency, the counts difference 
increase stably at the same rate with beam time. This suggests it's not 
bit flips. Similar inconsistency is also seen on gated sclars, which to 
be summarized later.
